When using elimination to solve 2x-3y = 4 7x+ 6y = -1 what would be a possible ﬁrst step? A 4x – 6y = 8 7x + 6y = -l B x = 3/2y + 2 7x + 6y = -1 C 2x -3y = 4 x = -6/7y – 1/7 D y = 2/3x – 4/3 7x + 6y = -1

Answers

Answer 1

Answer: A because you have to multiply the problems to even in out
(2x-3y=4) x2
(7x+6y=-1) x1

4x – 6y = 8
7x + 6y = -l

Answer:

J. $-(1)/(36)$ , $(1)/(216)$ , $-(1)/(1296)$

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

$-36, 6, -1, (1)/(6),...$

Here $a_1=-36$ and common ratio $(r) = (-1)/(6)=(-1)/(6)$ .

The formula we will use to find the next three terms is:

nth term = $a_1 * r^((n-1))$

5th term = $-36 * (-1)/(6)^((5-1))$ = $-(1)/(36)$

6th term = $-36 * (-1)/(6)^((6-1))$ = $(1)/(216)$

7th term = $-36 * (-1)/(6)^((7-1))$ = $-(1)/(1296)$

Answer:

J

Step-by-step explanation:

Find the common ratio r of the geometric sequence then multiply a term by r to obtain the next term

r = $(a_(2) )/(a_(1) )$ = $(6)/(-36)$ = - $(1)/(6)$

The next 3 terms are

$(1)/(6)$ × - $(1)/(6)$ = - $(1)/(36)$

- $(1)/(36)$ × - $(1)/(6)$ = $(1)/(216)$

$(1)/(216)$ × - $(1)/(6)$ = - $(1)/(1296)$

Who made more choices commission this month? How much did she make? Salesperson A made 11% of $67,530. Salesperson B made 8% of $85,740.

Answers

Answer Step-by-step explanation:

$Salesperson~A=$ $11$ % $of~67,530=(11)/(100) *67530=0.11$

$=0.11*67530=7,428.3$

$Salesperson~B=$ $8$ % $of~85,740=(8)/(100)*85740= 0.08$

$=0.08*85740=6,859.2$

$7,428.3$ > $6,859.2$

$Thus,~Salesperson~A~made~more~commission~than~Salesperson~B.$

giving brainiest

Answers

20+4(3x-5)+2x=28

We move all terms to the left:

20+4(3x-5)+2x-(28)=0

We add all the numbers together, and all the variables

2x+4(3x-5)-8=0

We multiply parentheses

2x+12x-20-8=0

We add all the numbers together, and all the variables

14x-28=0

We move all terms containing x to the left, all other terms to the right

14x=28

x=28/14

x=2

The answer is
20+4(3•2-5)+2•2=28
